On July 5, 2018, the women's pole vault competition took place at the IAAF Diamond League in Lausanne. American athlete Sandi Morris came in 4th place.

Morris tied New Zealand pole vaulter Eliza McCartney in fourth place with a clearance of 4.72 meters. They were both unsuccessful at three attempts at 4.82 meters.

Russian pole vaulter Anzhelika Sidorova came in third place with a new season best of 4.82 meters, which she cleared on her third attempt. American pole vaulter Jennifer "Jenn" Suhr finished in second place with 4.82 meters, which she cleared on her second attempt. 2017 world champion Katerina Stefanidi (who competes for Greece) came in first with a clearance of 4.82 meters on her second attempt, but the count-back rule (of fewer misses) worked in her favor for the first place win.

In the IAAF Diamond League rankings, Morris is still in first place, thus far, with 27 points. There are three remaining IAAF women's pole vault competitions this year in Monaco, Birmingham and Zurich.
